TECHNOLOGY OF MANUFACTURING UNIVERSAL CLUTCHES FOR
WITHOUT WELFARE, WITHOUT CUT-OFF, WITHOUT-FLANGE CONNECTION OF PIPE CUTS
IN HIGH PRESSURE PIPES
Kascheev Vladimir Sergeevich
Manufacturing technology of universal coupling for weldless, threadless, flangeless connection of pipe sections in pipelines with a nominal working pressure of 150 or more atmospheres. The implementation period is 1.5-3 months.
I have developed a technology for manufacturing universal couplings made of various materials for the WITHOUT WELDING connection of pipe sections (metal and plastic) of various diameters and purposes. This connection method differs from the well-known Georg Fisher technology in that pipe sections are not fixed by compressing sealing material around the pipe, which does not ensure the connection strength at high pressure and when pipes are in a vertical plane, but by mechanical fixation of pipe sections in the coupling.
The strength of my connection is comparable to the strength of a solid pipe with a nominal operating pressure of up to 150 atm . In addition, the method of the proposed connection, carried out manually, eliminates significant physical effort during installation. The use of a new coupling excludes threading and welding flanges. Connection and carried out at different angles.
The value of the coupling lies in its universal application, but above all in its use in harsh working conditions: in mines with gassed air and increased explosive hazards, in factories, etc.
